Looking for someone in Oswego Co., New York

Hoping some brave soul can help me out. I'm looking for a marriage record for Frank Olin to Roxey (?) in 1850 or 1851. It appears to be a first marriage for Frank but a second for Roxey. It appears they married in Oswego Co, possibly the town of Albion. I've been looking on line for a database, but no luck. Checked with the Oswego County Clerks office, they didn't keep records until 1881.

Can anyone help? This frank may be the son of John C. Olin and Roxanna Whitehead. Until I can find documentation showing parents, I won't know.

Thanks

Sherry
